Some issues about the bls.cpp #121
Comments
|
Read the comments at the start of bls.cpp
You need to link in the pairing code, e.g.
g++ -O2 bls.cpp* bn_pair.cpp* zzn12a.cpp ecn2.cpp zzn4.cpp zzn2.cpp big.cpp
zzn.cpp ecn.cpp miracl.a -o bls

the following problems.
The problem looks like the miracl.a has not compiled the pairing_3.h? So,
how can use the Elliptic curve in miracle？Do I need to modify the file
linux64_cpp? Hope you can help me solve this problem.

Hi, I am new to the miracl. When using this library, I meet some issues about the pairing operation. I first compile miracl follow the first.txt and I choose to bash linux64_cpp. However, when I test the bls.cpp, we meet the following problems.
The problem looks like the miracl.a has not compiled the pairing_3.h? So, how can use the Elliptic curve in miracle？Do I need to modify the file linux64_cpp? Hope you can help me solve this problem.
